Application `filed November 3, 1916. SeriaI No. 129,394.

To all 'whom it may-concern.' j

Be it known that I, HENRY H. Asi-moon, a citizen of the United States, residing at San Diego, in the county of `San Diego. and State of California, have invented `certain new and useful Improvements in Oil-lBurners, of which the following is aspecification.

My invention relates to improvements in oil burners for use in connection with cook,- ing and heating stoves, ranges, boilers, furnaces-and the like, more particularly to that class of `burner which utilizes crude oil or stove distillate and steam in combination as a fuel. rlhe objects of my invention are: first, to improve the general form vand construction of `the `oil burner patented by me June S, 1909, Patent Number 924,216 for oil burners; second, to provide 'an oil burner in which steam is produced from water by the burner itself for aiding in the fuel combustion .and distribution of the heat; third, to provide a burner of this class with alcovering that will protect `certain portions `of the burner and prevents its being overheated and warping, and, fourth, to provide a burner with a generator plate for generating gas from the oil until the water is converted into steam after which the oil is sprayed over the parts of fire brick and aiding the combustion thus reducing the carbon and soot to a minimum, and, fifth, to provide an oil burner of this class which is simple and economical of construction, durable, easy to ignite, easy to operate and will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts as will hereinafter be described in detail and particularly set forth in the appended claim, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this specification, in which:

Figure 1 is a longitudinal sectional view through the middle thereof of the form of my device to be used in cooking stoves showing a portion in elevation to facilitatethe illustration. Fig. 2 is a top view thereof with the supporting plate 6 removed. Fig. 3 is a fragmentary top view of the same with said plate positioned thereon. Fig. 4 is a sectional view through the middle thereof of the steam nozzle shown positioned relatively to the oil inlet pipe, a fragmentary portion of which is shown. Fig. 5 is a front view of said steam nozzle shown positioned relatively toa fragmentary portion of the oil inlet. Fig. 6 is a longitudinal sectional view through the middle thereof of a modified form of the burner adapted for use with furnaces and boilers. Fig. 7 is a transverse sectional view thereof through 1 1 of Fig. 6. F ig. S is a fragmentary top view thereof. Fig. ,9 is a perspective view of the inclined generating plate and Fig. 10 is a perspective view of the modified forni of burner without the portions of fire brick and the inclined generating plate. v

Similar characters of reference refer to similar parts throughout `the several views.

The pan 1, inclined generating plate 2, brick 3, steam pipe l, oil pipe 5, and supporting plate 6 constitute the principal parts of `my oil burner.

rlChe pan 1 is shallow and elongated in shape and it is provided with a pair of` tapering ribs l*L upon which is loosely mounted the inclined generating plate 2 which is provided around its Vouter edge with a flange 2 adapted to prevent the oil from running off at the edge. On top of this inclined `plate 2 in the pan 1 is heaped a mass of broken pieces of lire brick. Mounted on said pieces of fire brick and partially supported by said fire brick and the inclined generating plate 6 is the steam pipe 4E, the one end of which communicates with any desired water supply and extends down through the plate 6, and out over the pan 1 and the pieces of fire brick 3 and forming a loop over said pan in the course of the blaze from the burner and its otherI end extends backward to the opposite end of the pan 1 at right angles and then over tlie middle to adjacent the center of the support 6 and it is provided on its extended end with the nozzle la which is an ordinary pipe cap provided with a pair of slits therein placed in horizontal position to permit the exit of steam from the pipe formed by the heat of the water in the pipe by the burner. The one end of the oil pipe 5 extends in a vertical position so that its end is adjacent to and just over said nozzle la positioned as shown best in Figs. 4 and 5 of the drawings. This oil supply pipe extends upwardly through the support 6 and to any oil supply reservoir as desired. The supporting plate 6 is disk shaped and is provided centrally with a damper 6a surrounding the oil pipe adapted to provide and regulate the draft to the` burner.

In the modied form Vof construction shown in Figs. 6, 7, 8, 9 and 10 of the drawings the pan l is provided with a hood 7 which incloses the burner except on one side thereof, the direction in which the blaze eX- tends. In the top of this hood the steam and oil supply pipes are supported instead of in the plate 6in the other form of con` struction, and there is provided two apertures 7a from the top side thereof for providing draft to the burner, and in the back side there is provided a damper 7 b for regulating the air to said burner. Otherwise the construction is the same as that described in the other form of burner.

Though I have shown and described a particular construction and a particular modified form thereof, I do not wish to be limited to this particular construction and its modification, but desire to include in the purview of my invention the construction, combination and arrangement substantially as set forth in the appended claim.

Y It is obvious that with this construction there is provided an oil burner which produces steam from water and uses the same Copies of thisV patent may be obtained for warping, that the steam and oil in the proper regulated quantities will provide a fuel that will produce a maximum of efliciency and a minimum of carbon or soot, that the device as a Whole is simple and economical of construction, durable, easy to operate, easy to light and will not readily deteriorate or get out of order.

Having thus described my inventiomwhat I claim as new and desire to secure by Letters Patent is:V i 'Y In a device of the class described, the combination of an elongated pan providedwith vertical ribs longitudinally therewith, an inclined generating plate supported by said ribs in said pan provided with an upwardly extending` fia-nge around its outer edge, fire brick mounted on `said inclined plate, a water and steam conducting pipe `mounted over said lire brick and plate, av nozzle at one end of the steam pipe provided with slotted apertures, and a fuel oil conducting pipe positioned so that its exit terminates just above and in front of said slotted aper` tures whereby steam is produced in said water conducting pipe by said burner and contacting with said fuel oil supply sprays the same and forms a combination oil and steam fuel.

In testimony whereof, I have hereunto set my hand at San Diego, California, this 28th day of October',1916. Y
